The remove() method in the Queue interface ________.

A. retrieves, but does not remove, the head of this queue, returning null if this queue is empty

B. retrieves and removes the head of this queue, or null if this queue is empty

C. retrieves, but does not remove, the head of this queue, throwing an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

In Java, the Queue interface is found in the java.util package and inherits from the Collection interface. It is used to store elements which are processed in the order in which they are inserted. This means that the first element will be processed first.

The Queue interface has many methods. Some of them are;

i. add(): allows elements to be added to the queue.

ii. remove(): retrieves and removes elements from the head of the queue. The head of the queue points to the first element of the queue. If the queue is empty, the remove() method throws an exception called the NoSuchElementException

iii. poll(): retrieves and removes the element at the head of the queue. Unlike the remove() method, if the queue is empty, a null is returned.

iv. peek(): retrieves but does not remove the element at the head of the queue. Just like the poll() method, a null is returned if the queue is empty.

Answer:

hard copy attachments

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.

One of the most widely used communication channel or medium around the world is an e-mail (electronic mail).

An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.

The following documents or files such as soft copy attachments, web links and web pages may be sent from one user to another through the use of an email.

However, hard copy attachments cannot be sent via email because they're physical documents and as such requires that they be delivered physically to the recipient.

In conclusion, you can only send soft copy documents that you cannot feel or touch with your hands over the internet and via email. Thus, an email is only designed to accept soft copy documents or files (attachments) but certainly not hard copy documents (attachments) in our technological era.

The electromagnetic spectrum consists of various waves. The Radio waves are categorized to be at the low-frequency end of this spectrum.

Radio Waves have multiple communication uses. Some of them are television and radio broadcasting, communications, and satellite transmissions.

Radio waves are not harmful to biotic life when absorbed by living matter and their transmission is unimpeded by air. Their transmission can also be absorbed, deflected, reflected, refracted, or diffracted by air molecules and the earth's surface.

The date Friday 26, May 2017 represents 2/5 of the year 2017

From the question, we understand that Ramadan starts on Friday 26, May 2017.

Using Microsoft Office Excel, this date is the 146th day of the year in 2017.

Also, 2017 has 365 days.

This is so because 2017 is not a leap year.

So, the fraction of the year is:

[tex]\frac{146}{365}[/tex]

Multiply the fraction by 73/73

[tex]\frac{146}{365} = \frac{146}{365} \times \frac{73}{73}[/tex]

Simplify

[tex]\frac{146}{365} = \frac{2}{5}[/tex]

Hence, the fraction of the year is 2/5

The fraction of the year that corresponds to the Islamic month of fasting, Ramadan, beginning on May 26, 2017, is 2/5.

Find out how many days passed from January 1, 2017, to May 26, 2017.

Total days = 31 + 28 + 31 + 30 + 26

Total days = 146 days.

The total days in regular year:

The total days = 31 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31

The total days  = 365 days.

The required fraction is calculated as:

Fraction = 146 days / 365 days

Fraction = 2 / 5

So, the fraction is 2 / 5.

Answer:

Non-volatile memory (NVM) is a type of memory that retains stored data after the power is turned off. Unlike volatile memory, it does not require an electric charge to maintain the storage state. Only reading and writing data to non-volatile memory requires power.

Answer:

The algorithm is as follows:

Input number  

count = 0

while(number not equal 0)

   number = number / 10

   count = count + 1

end

Print count

Explanation:

This gets input for the integer number

 Input number  

This initializes count of digits to 0

count = 0

The following loop is repeated while number is not 0

while(number not equal 0)

This performs integer division of the number by 10; the resulting division is saved in variable number

   number = number / 10

The count variable is incremented by 1

   count = count + 1

The loop ends here

end

This prints the count of integers

Print count

Answer:

=B3 / 4

Explanation:

The price of a packet of grated cheese is $2.60. To make pizza, this packet of cheese is divided into four to make 1 pizza. Therefore, the price of the grated cheese used to make 1 pizza = price of packet of cheese / 4 = $2.60 / 4 = $0.65

This price is the price inserted in cell D3. The price for each packet of grated cheese is inserted in cell B3.

Therefore the formula used in cell D3 to find the price of each grated cheese required for one pizza is:

Formula for D3 is "=B3 / 4"
